title: Syntheses of novel 3-amino-2(1H)-thioxo-4(3H)-quinazolinones and evaluation of their immunotropic activity. Part III.
abstract: The synthesis of two series of derivatives containing the quinazolinone-4 moiety is described. 3-Amino-2(1H)-thioxo-4(3H)-quinazolinone (1) was subjected to reactions with halogenoketones and halogenoaldehydes, leading to the production of the corresponding ketones, aldehydes, Schiff bases, and 6-oxo-1,4,5-thiadiazin[2,3-b]quinazoline derivatives. Subsequently, 1 was condensed with selected alpha, beta-unsaturated carbonyl compounds, aldehydes, ketones, acid chlorides, and esters. The compounds were tested for their potential activity in a model of humoral and cellular immune response. The tests showed that the compounds exhibited differential immunotropic activities. Of particular interest is compound 19, exhibiting a strong stimulatory activity with regard to cellular immune response and compound 16 exerting a strong inhibitory action in both types of the immune response.
